AUTOMATIC ATOMIZER FOR INTERNAL-COMBUSTION ENGINES re ress.

To all whom it may concern. v

Be it known that I, EMILE VVALnMErrm,

a citizen of the United States, and a. resident of Gulfport, in thecounty of Harrison and State of Mississippi, have invented a certain newand useful'l mprovement in Automatic Atomizers for nternal-CombustionEngines, of which the following is a specification My invention relatesto improvements in devices for injecting water in an atomized state intoan internal combustion engine, and it consists in the combinations,constructions, and arrangements herein described and claimed. e

An object of my invention is to provide a simple device, by means ofwhich the water from the water jacket of the engine may be automaticallydrawn into the intake manifold of an internal combustion engine, therebymixing with the fuel and air, to cool the engine and to reduce thedeposit of carbon in the cylinders.

A further object of my invention is to pro videa device which may hereadil y attached to the intake manifold of any internal com- .bustionengine, and which will thereafter work automatically to effect theinjection of the atomized water.

Other objects and advantages will appear in the following specification,and the novel" features of the invention will be particularly pointedout in the appended claims.

My invention is illustrated in the accompanying drawings, forming partofthis application, in which:

Figure l is a side view showing my device applied to an engine.

Fig. 2 is a section along the line 22 of Fig. 1. I

Fig. 3 is a section along the line 3-3 of Fig.2. v

Fig. 4 is. a perspective view of the valve.

In carrying out my invention, I provide a body portion 1 which is hollowand which has at one end a threaded extension 2, this extension beingarranged to enter a threaded bore 3 in the intake manifold At theopposite end of the hollow body portion 1 is a hinged plate 4 which hassmallperforations The plate 1s hinged to the body portion at 5 in such'a manner that it is free to move toward 'and'aw ay from the bodyportion, in the manner here nafter explained.

At 6 I have shown an extension of the Specification in letters Patent.

body portion 1, which constitutes in fact a valve casing. This casing-contains a valve;- 7, whose valve stem 7' projects into the'iiiteriorof the body portion 1. Thevalve 7 is normally retained on its seat bymeitnri of a spring 8, the tension of the spring being regulated by ascrew plugv h. 1

' A threaded cap 10 carriedby the body portion 1. Thih. ca llS providedwitha series of openings 10*; .Zill encap bears a revoluble plate 11having openings 11" arrangedto. register with the'openings 10 Athumbscrew 12 is used to lock the plate 11 in its adjusted position.

The valve easing G may. be pht into communication with the interior ofthe water jacket of one of thecylinders 13,'by means of a pipe 14, seeFig. 1, a union 15, secu-ringthe pipe to the valve casing- From theforegoing description of the various parts of the device, the operationthereof may be readily understood.

Normally the position of the plate 4 is that shown indotted lines inFig. '2. This plate 4, it will be observed, has an arm 17 on its innerface, the end of the arm being arranged to engage the end of the valvestem 7 when the plate is drawn inwardly.

The arm 17 has weight enough to cause-the 1 plate 4 to assume the dottedline position as stated.

Normally the valve 7 is against its seat, so as to shut off any flow ofwater from. the water jacket through the pipe 14. Now when the engine isstarted up, the suction in the in the cap 10.

cylinders will cause the plate 4 to be moved from the dotted lineposition to the full line position shown in Fig. 2, the arm 17 Willengage the end of the valve'st em 7", thus unseating the valve 7 andpermitting a flow of water from the water jacket through the pipe 14,and into the interior of the body portion 1. Air is also drawn throughthe alined openings 11" and 10, and through the perforations fi. Thisair will cause the water to be blown into the intake manifold, and thefine streams of air through the open ings 5 will atomize the water. Inorder to further atomize the water I provide a screen 18 so that whenthe Water finally passes into the interior of, the intake manifold 3 itis in the form of mist or vapor. This is carried. into the interior ofthe cylinders, and tends to coolthe latter, as well as to prevent thedeposit of carbon. As-soon as the engine stops working, the plate 4drops back and i the valve 7 is seated against its seat, being heldthere by the spring 8 so that the flow of-Water i s'now cut off.

I am aware that it-is broadly old to inject Wateriinto theintakemanifold of internal combu t n engines. Such isnot my invention; 5;invention comprises adevice-in which thewater from the water jacket may'be atomized "bymeans of a cool stream of manand blown with theair intothe intake does not come in contact with the air.

' manifold, thus arriving in the cylindersat a lower temperature thanwhere the steam, for instance, from the water. jacket is admitteddirectly to the intake manifold and invention furtheiwlies in theprovision of means for automatically controlling the valve which admitswater into the intakemanifold by the air itself.
